The southern North Sea is a particularly important area for understanding the behaviour of the British-Irish Ice Sheet (BIIS) during the last glacial cycle. It preserves a record of the maximum extent of the eastern sector of the BIIS as well as evid...

A stratigraphic investigation of the Celtic Sea megaridges based on seismic and core data from the Irish-UK sectors (2018)
Journal Article

A stratigraphic investigation of the Celtic Sea megaridges based on seismic and core data from the Irish-UK sectors. Quaternary Science Reviews, 198, 156-170. https://doi.org/10.1016/j.quascirev.2018.08.029

The Celtic Sea contains the world's largest continental shelf sediment ridges. These megaridges were initially interpreted as tidal features formed during post-glacial marine transgression, but glacigenic sediments have been recovered from their flan...

Lack of evidence for a substantial sea-level fluctuation within the Last Interglacial (2018)
Journal Article

During the Last Interglacial, global mean sea level reached approximately 6 to 9 m above the present level. This period of high sea level may have been punctuated by a fall of more than 4 m, but a cause for such a widespread sea-level fall has been e...

Ice margin oscillations during deglaciation of the northern Irish Sea Basin (2018)
Journal Article
Chiverrell, R., Smedley, R., Small, D., Ballantyne, C., Burke, M., Callard, S., Clark, C., Duller, G., Evans, D., Fabel, D., van Landeghem, K., Livingstone, S., Ó Cofaigh, C., Thomas, G., Roberts, D., Saher, M., Scourse, J., & Wilson, P. (2018). Ice margin oscillations during deglaciation of the northern Irish Sea Basin. Journal of Quaternary Science, 33(7), 739-762. https://doi.org/10.1002/jqs.3057

We present a new chronology to constrain ice‐margin retreat in the northern Irish Sea Basin. Estimates on the timing of ice thinning derived from surface exposure ages for boulders from the summits of the Isle of Man and south‐west Cumbria suggest th...

Submarine deglacial sediment and geomorphological record of southwestern Scotland after the Last Glacial Maximum (2018)
Journal Article

Understanding the style and pattern of retreat of the offshore sectors of the last British-Irish Ice Sheet (BIIS) is critical to any attempt to reconstruct its history following the Last Glacial Maximum (LGM). This paper presents a new seismo-stratig... Read More about Submarine deglacial sediment and geomorphological record of southwestern Scotland after the Last Glacial Maximum.

Glacigenic sediment fans recording shelf edge deposition from marine-terminating ice sheets have previously been recognised along the NW European continental margin from Svalbard to as far south as Donegal, off north-west Ireland. Here we present evi... Read More about A Plio-Pleistocene sediment wedge on the continental shelf west of central Ireland: The Connemara Fan.

The Disko Trough-Mouth Fan (TMF) is a major submarine sediment fan located along the central west Greenland continental margin offshore of Disko Trough. The location of the TMF at the mouth of a prominent cross-shelf trough indicates that it is a pro...

Quaternary evolution of high-latitude margins has, to a large degree been shaped by the advance and retreat of ice sheets. Our understanding of these margins and the role of ice sheets is predominantly derived from the polar North Atlantic during the...
